examples of food chains grade 6

📚 Quick Study Guide

🔍 A food chain shows how energy and nutrients move from one organism to another in an ecosystem. 🌿 It always starts with a producer (like a plant) that makes its own food through photosynthesis. 🐛 Then comes a consumer, which eats the producer. This could be an herbivore (plant-eater) or an omnivore (eats both plants and animals). 🦊 Next, there might be another consumer that eats the first consumer. This is often a carnivore (meat-eater). 🍄 Decomposers (like fungi and bacteria) break down dead organisms and return nutrients to the soil. ☀️ The original source of energy for almost all food chains is the sun. 🔗 Food chains are interconnected, forming complex food webs.
